Using Windows HPC Server Log Files

Updated: July 7, 2010

Applies To: Windows HPC Server 2008

This topic contains information about the location and contents of log files in Windows® HPC Server 2008. You can use the information in the log files to help troubleshoot the services and operations in Windows HPC Server 2008.

To verify that the necessary Windows HPC Server 2008 and other services are running and configured properly on specific nodes in the cluster, you can run the All Services Running and the Service Configurations Report diagnostics on the nodes. For more information, see Run Diagnostic Tests.

By default, the Windows HPC Server 2008 service log files show error messages and warning messages only. You can configure the logging level in the Windows HPC Server 2008 service log files to display more or fewer messages. For example, you might want to enable the logging of trace messages to troubleshoot the operations on a cluster node.

To change the logging level, you configure the value of the TraceLevel registry key. The valid values of TraceLevel are in the following table:

TraceLevel value

Description

0

No logging

1

Log error messages only

2

Log error and warning messages only

3

Log error, warning, and information messages only

4

Log error, warning, information, and trace messages

Caution

Setting TraceLevel to 4 can greatly increase the size of the service log files and can affect the performance of the head node. It is recommended that you use this setting only temporarily to help troubleshoot an issue.

Caution

The following procedure includes steps to modify the registry. Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

The HPC Basic Profile Web Service on the head node provides access to the HPC Job Scheduler service using a web service protocol. If the HPC Basic Profile Web Service is activated, the following log files for the service are generated by default in the %CCP_HOME%\Bin\ folder:

Log file

Description

HPCBasicProfile.svclog

Generated by the HPC Basic Profile Web Service.

A log of errors and information about how the HPC Basic Profile Web Service is working.

HPCBasicProfileWCF.svclog

Generated by the WCF hosting environment.

A log of message traffic going in and out of the HPC Basic Profile Web Service.

Note

The log files for the HPC Basic Profile Web Service are recorded in a text-based XML format that can be browsed using the Service Trace Viewer Tool (SvcTraceViewer.exe) that is part of the .NET 3.0 (and later) redistributable package. Alternatively, you can use any text file editor to view the messages.
